1.7 Safety Precautions
Warning!
Always completely disconnect the power
cord
from
your chassis
whenever you work with the
hardware. Do not make
connections while
the
power
is on.
Sensitive electronic components
can
be
damaged
by sudden power surges. Only
experienced electronics personnel should open
the PC
chassis.
Caution!
Always ground yourself to
remove any static
charge
before touching the motherboard. Mod-
ern electronic devices are very sensitive
to
static
electric charges.
As a safety
precaution,
use a grounding wrist
strap at all times. Place
all
electronic components on a static-dissipative
surface
or in a static-shielded
bag
when they
are not in the
chassis.
Caution!
The computer is
provided with a battery-pow-
ered
Real-time
Clock circuit. There is a danger
of explosion if battery is incorrectly replaced.
Replace only with
same or
equivalent type
rec-
ommended by
the manufacturer. Discard
used
batteries according
to manufacturer's
instruc-
tions.

incorrectly installed. Do not attempt
to
recharge,
force open, or
heat the battery.
Replace the battery only

or
equivalent
type recommended
by the manufac-
turer. Discard used batteries
according to the
manufacturer’s instructions.
